| Abstract: | Gas phase nitration of benzene on ZSM-5 zeolite has been studied at 140–170°C. Increase in the HNO3/C6H6 ratio of the starting mixture was shown to increase the nitrobenzene yield. Process parameters worsened with time since reagents
and products were strongly adsorbed and left the zeolite surface only at 220–250°C as CO, CO2 and NO. |
